I have a Redarc low coolant alarm in the radiator. I have misplaced the actual heat sensor electrical connector, so made contact with Redarc as I could only buy a kit containing a number of items for $80. I only need the clip. Customer service told me the clip was not avail individually but supplied me with the names of 4 spares places where I could buy one. So headed out today in 33 Deg heat and not one had seen one, not stocked, goodbye. I went back to Redarc with the message and was told, well that a surprise as they have bought them from NARVA in the past - Narva not on the list, so followed the link supplied and it is for a totally different clip and avail only in a pack of 100 for $60. So back to Redarc to give them the feedback. Finally they decided to supply me the entire $80 kit for free, including postage - unbelievable customer service. Maybe these guys are worth the extra dollars they charge? Anyway, its a good news story and customer service came thru for a change.
